Zb all whom it may concern:

Be it known that I, ESOM O. LEACH, a citizen of the United States ofAmerica, residing at Fairmount, in the county of Grant and State ofIndiana, have invented certain new and useful Improvements inMold-Sanding Machines, of which the following is a specification,reference being had therein to the accompanying drawings. a

This invention relates to mold sanding machines to be used in connectionwith steam power brick making machines.

The object of the invention is to dispense with the help usuallyrequired for sanding the molds, increase the output of a machine ofgiven capacity, preventing the waste and the scattering of the sand andobtain an even and uniform sanding of the molds.

The improvement consists of the organized machine and the novelconstruction and combination of the parts which will hereinafter be morefully described and claimed.

In the accompanying drawings,--Figure l is a side elevation of a machineembodying the invention, showing the operation of the same, a moldaboutto be dropped into the sand box, one in position to be removed andothers sanding. Fig. 2 is a top plan view of the machine. Fig. 3 is adetail view of the adjustable bearings and the means for moving the sameto throw the machine in and out of gear.

Similar letters referto corresponding parts in the several views.

The sand box is composed of two ends or heads A, preferablyof cast iron,and a semicircular casting B, of sheet metal, steel being preferred. Theedges of the casing are let into grooves provided in the heads and thelatter are secured in place in any desired manner preferably by the rods0, which pass through apertured cars a, on the heads.

A shaft D, journaled in the heads A, is provided at one end with a gearwheel d, meshing with a pinion f, on a short shaft F. Upon'this shaft D,is mounted the mold carrier consisting of heads G, and sand lifting.

plates H. The heads G, are open spiders, the spokes radiating from tubeskeyed to the said shaft D. The perimeter of the heads has acorresponding series of straight faces a, j, k. The faces 70, extendapproximately gradial'ly and the faces j, at right angles to fthefaces7c. The faces 11, incline from the faces is, and form seats for theplates H, ,1 which are secured thereto. The contiguous faces j,.and lc,form seats for the molds, one i closed side of the mold resting on theface It, and the open side on the edges j. The forward or advancingedges h, of the plates H, project beyond the faces It, to approach closeto the bottom portion of the casing 13, to scrape up the smallest amountor quanity of sand in the box. The plates may be imperforate or haveopenings as required.

A bracket K, is attached to the head of the box and forms a support fora movable hearing box is, in which is journaled the shaft F. Parallelslots are provided in the brackets to receive bolts n, by means of whichthe said bearing box is held on the brackets. shaft 0, journaled in thebearing box 70, and adapted to be turned by a suitable handle 0, has aneccentric portion p, which works in a transverse slot P, in the bracketK. On

turning the stub-shaft the bearing box will bemoved to bring thepinionf, in or out of gear with the gear wheel d, as required. The bandwheel Q, is keyed on the shaft F. The gearing is such that when themachine is run at the required speed a mold will be sanded and broughtinto position for removal at each operation of the plunger of the brickmaking machine. In the machine shown four sets of edges Lj, 7c, arerepresented. It will be understood that this number may be varied tosuit the capacity of the machine.

When in operation the mold carrier is rotated in the direction of thearrow shown in Fig. 1, the molds being placed in the sand box at S, andremoved therefrom at T. The box is filled with sand to the depth of fiveor six inches. The faces in, engage witha closed side of the mold andcarriesthe latteraround to the position T where it is supported by theface j. The plates H, scoop up the sand and throw it into the moldimmediately in the rear and following said plate.

I claim 1. In a mold sanding machine, a rotary mold carrier having headsdisposed about their peripheries in co-incident relation a series offaces, some of which extend approximately radially from the carrier,others at Astub- ICO right angles to the radial faces, and othersinclining from the said right angularly disposed faces and locatedbetween them and the said lateral faces, and sand lifting plates securedto the inclined faces, subtantially as described.

2. In a mold sanding machine, a rotary mold carrier comprising headsmounted upon a shaft and located a distance apart, and having formed intheir edges a series of faces, some on radial lines, others at rightangles to the radial faces, and some inclining from the relativelydisposed faces and located between them and the radialfaces, and sandlifting plates extending across the space between the heads and fixedlysecured to the inclined faces and having their advancing edges projecting beyond the radial faces, substantially as described.

3. The herein specified sand molding machine, composed of asemi-circular casing, ends having grooves on their inner faces to to theshaft, one near each end, and havingv radial faces, seats at rightangles to the said faces, and inclined edges between the seats and thesaid faces, and sand lifting plates secured upon the inclined edges andextending across the space between the spiders, and having theiradvancing edges projecting beyond the radial faces, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

ESOM O. LEACI-I.
